UCS2113T-2C-V/G4 Equivalent & Substitute Parts

Part Overview

The UCS2113T-2C-V/G4 is a Dual USB Port Power Switch manufactured by Microchip Technology, classified as a Power Management Integrated Circuit (PMIC). This component functions as a Power Switch/Driver with 1:1 ratio configuration, delivering up to 3A output current across two high-side switched outputs. The device operates within the 4.5V to 5.5V supply voltage range and supports I2C and SMBus interfaces for digital control. The part is Active in product status and RoHS3 compliant. Equivalent substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part number becomes unavailable or when design requirements necessitate alternative sourcing options.

Substitute Part Grouping Explanation

Substitute parts for the UCS2113T-2C-V/G4 are identified based on strict parametric equivalence within the UCS2113 product family. The substitution logic is governed by the following critical parameters that must remain identical across all equivalent parts:

Mandatory Matching Parameters:

• Manufacturer: Microchip Technology
• Switch Type: USB Switch
• Number of Outputs: 2
• Ratio - Input:Output: 1:1
• Output Configuration: High Side
• Interface: I2C, SMBus
• Voltage - Load: 2.9V ~ 5.5V
• Voltage - Supply (Vcc/Vdd): 4.5V ~ 5.5V
• Current - Output (Max): 3A
• Rds On (Typ): 40mOhm
• Input Type: Non-Inverting
• Fault Protection: Current Limiting (Fixed), Over Temperature, Over Voltage, UVLO
• Operating Temperature: -40°C ~ 105°C (TA)
• Mounting Type: Surface Mount
• Package / Case: 20-VFQFN Exposed Pad
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 3 (168 Hours)
• REACH Status: REACH Unaffected

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. The UCS2113T-1C-V/G4 satisfies all mandatory matching parameters and is therefore a valid equivalent substitute.
